$f \left(x\right) = {5}^{- 2 x + 3}$

$g \left(x\right) = - {6}^{x + 5}$

#### Explanation:

To solve with a graphing calculator, you would first graph the function

$f \left(x\right) = {5}^{- 2 x + 3}$

Then also graph this

$g \left(x\right) = - {6}^{x + 5}$

Now you solve for the intersections using your graphing utility.
